aarch64: Add support for Armv9.1-A to Armv9.3-A
This patch adds AArch64 support for -march=armv9.[123]-a. The behaviour of the new options can be expressed using a combination of existing feature flags, so we don't need to eat into the vanishing number of spare AARCH64_FEATURE_* bits. Hoewver, it was more convenient to separate out the |s of feature flags so that Armv9.1-A could reuse the set for Armv8.6-A, and so on. include/ * opcode/aarch64.h (AARCH64_ARCH_V8_FEATURES): New macro, split out from...
